摘要
In the light of sustainability, the nearly forgotten control of relative humidity (RH) in display cases with saturated salt solutions is re-evaluated. Spilling and creeping of salts can be avoided. By choosing magnesium nitrate or potassium carbonate, the temperature dependence of the RH and the emission of harmful gases are negligible. Measurements with metal oxide semiconductor (MOS) gas sensors showed such solutions to be excellent absorbers for corrosive pollutants such as acids and aldehydes, especially the alkaline potassium carbonate (hitherto not used in museums). The practical application of such solutions in display cases is currently being tested in a community science project in a number of museums. This will result in improved guidelines for conservators and it is hoped, in a revival of this passive, failsafe, low-carbon footprint technique. Desde el punto de vista de la sostenibilidad, se reeval & uacute;a el casi olvidado control de la humedad relativa (HR) en las vitrinas con soluciones salinas saturadas. Se pueden evitar derrames y filtraciones de sales. Al elegir nitrato de magnesio o carbonato de potasio, la dependencia de la temperatura relativa de la HR y la emisi & oacute;n de gases nocivos son insignificantes. Las mediciones con sensores de gas semiconductores de & oacute;xido met & aacute;lico (MOS) mostraron que estas soluciones son excelentes absorbentes de contaminantes corrosivos como & aacute;cidos y aldeh & iacute;dos, especialmente el carbonato de potasio alcalino (hasta ahora no utilizado en museos). La aplicaci & oacute;n pr & aacute;ctica de estas soluciones en vitrinas se est & aacute; probando actualmente en un proyecto cient & iacute;fico comunitario en varios museos. Esto dar & aacute; como resultado pautas mejoradas para los conservadores y se espera que resucite esta t & eacute;cnica pasiva, a prueba de fallas y de baja huella de carbono.
